Aristotelia plant named ‘Sobresale’

ABSTRACT

A new cultivar of  Aristotelia chilensis  plant named ‘Sobresale’ that is characterized by its vigorous plant habit, its glossy leaves that are dark green in color and its flowers that are light cream yellow to greenish yellow in color.

Botanical classification: Aristotelia chilensis.

Varietal denomination: ‘Sobresale’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent Applications filed for a plant derived from the same breeding program that are entitled Aristotelia Plant Named ‘Pretoria’ (U.S. Plant patent application Ser. No. 16/602,063), Aristotelia Plant Named ‘AZ50’ (U.S. Plant patent Ser. No. 16/602,061), and Aristotelia Plant Named ‘VB1’ (U.S. Plant patent Ser. No. 16/602,064).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Aristotelia chilensis and will be referred to hereafter by its cultivar name, ‘Sobresale’. ‘Sobresale’ represents a perennial evergreen shrub grown for landscape use.

‘Sobresale’ was discovered by the Inventor as a chance seedling in a trial field in Pitrufquen, IX region de la Araucanía, Chile in January of 2013. The field had been planted with numerous unnamed proprietary seedling plants from the Inventor's breeding program. The parentage is therefore unknown.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in summer of 2014 in Pitrufquen, IX region de la Araucanía, Chile. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Sobresale’ as a unique cultivar of Aristotelia chilensis.

-   -   1. ‘Sobresale’ exhibits a vigorous plant habit.     -   2. ‘Sobresale’ exhibits glossy leaves that are dark green in         color.     -   3. ‘Sobresale’ exhibits flowers that are light cream yellow to         greenish yellow in color.

‘Sobresale’ can be most closely compared to the Aristotelia chilensis cultivars ‘Variegata’ (not patented). ‘Pretoria’, ‘AZ50’, and ‘VB1’. ‘Variegata’ differs from ‘Sobresale’ in having variegated foliage. ‘Pretoria’ differs from ‘Sobresale’ in having a slightly wider plant shape, more green colored young stems, green young foliage and less glossy mature foliage that is less dark green in color. ‘AZ50’ differs from ‘Sobresale’ in having a wider plant shape, less glossy foliage and lighter green foliage. ‘VB1’ differs from ‘Sobresale’ in having yellow-green branches, less glossy foliage and darker and more yellow-green mature foliage.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Aristotelia. The photographs were taken of a 24-month-old plant (with a single prune 3 weeks prior) of ‘Sobresale’ as grown in an unheated greenhouse in a 30-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a view of the plant habit of ‘Sobresale’.

The photograph in FIG. 2. provides a close-up view of the flowers of ‘Sobresale’.

The photograph in FIG. 3 provides a close-up view of the young foliage of ‘Sobresale’.

The photograph in FIG. 4 provides a close-up view of the mature foliage of ‘Sobresale’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Aristotelia.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 24-month-old plants (with a single prune 3 weeks prior) of ‘Sobresale’ as grown in a greenhouse in 30-cm containers in Noordwijkerhout, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
